Abstract: The present invention provides a semiconductor laser module and a method for application in noninvasive medical treatment. The module comprises a direct-output type semiconductor laser light source and a beam shaping device disposed in the light-exit direction of the direct-output type semiconductor laser light source. The beam shaping device comprises a light reflection component. The light reflection component is configured to enable laser beams outputted by the direct-output type semiconductor laser light source to be uniform. Based on the semiconductor laser module and the method provided in the present invention, the objective of treatment can be achieved by means of extracorporeal irradiation in a case in which no harm is done to a human body, costs are low, and the treatment effect is good.

Abstract: Disclosed herein is a cooler of a semiconductor laser. The cooler includes a heat sink comprising a first surface and a second surface opposite the first surface; a first conductive layer and a second conductive layer, disposed on the first surface and not short-circuited to each other; and a conductive connector comprising a first end part, a second end part, and a first connection part connecting the first end part and the second end part. The first end part is on the first conductive layer. The second end part is on the second surface of the heat sink and insulated from the heat sink. The first connection part is disposed at a first non-opposite end of the first conductive layer on the heat sink.

Abstract: The invention provides a cooler of the semiconductor laser, a semiconductor laser comprising the cooler, and a stack of the semiconductor lasers, all of which can be applied to high power devices, and have high environmental adaptability and reliability.
